The Funds Management derivation tool can only be used to derive Funds Management account assignments. These include:
- Commitment item
- Funds center
- Functional area
- Funded program.
Within the derivation strategy, you can also use any other account assignments that are in the document to be posted but only FM account assignments can be transferred.
Using the Funds Management (FM) derivation tool (transaction FMDERIVE), you want to derive account assignments that are not Funds Management account assignments.
For example, you want to use a derivation rule to derive the G/L account, the cost center, or the business area. However, the affected account assignments are not transferred to the document.
Account assignments that do not belong to FM cannot be changed by the FM derivation tool. Otherwise, there could be major problems in other applications (FI, CO, and so on).
Depending on the affected applications, two similar methods are possibly available (validation and substitution, or similar).
